Taplabor cannot connect to Dropbox

I want to run an app demo for a client on the iPad. Purchased tap labor, as instructed. It fails to find any files, on multiple Dropbox accounts I have tried. Even though I see the folders and files. Any ideas? Purchased prototypes pro and tap labor ..feel like I wasted time and money...

Taplabor works with HTML files. A vp file is not HTML. So you need to open the .vp file with Prototyper first. Then select file -> Export to HTML and copy the resulting folder in your Dropbox account. Then you will be able to open it with Taplabor.
